eled face 9 of the block 7 soasto maintain thej aw ends 5?(? in substantially parallel relation in the operation of olampin a members.

The jaw member 5 hastwo angularly posed bores 14; and 15 arranged transversely thereof and in spaced parallel relation as clearly seen inFi'gi f the drawing, the bore 114 being controlled from the right hand'side of the member 5 and terminating short of the other side as indicated at 14 "whereas the bore 15 is controlled from the left hand side and terminates short of therighthandside as indicated at 15 and similar boresare formed i in the j aw member 6: i

U-shapedfcou lingand spacing pins 116 and l7 areemployed for coupling the members 5i and 6 togetherand also to cooperate wlth th-e side edges of the seraper tool -13 to p p r y align the same in and between'the ends 16 l-'17 are cut out to form 'keyways 16-17? inconnection with which a set screw 18 arranged in the part 5 is adapted to operate so, as'to'retain the-pins 16 and 17in different positions of adjustmentlaterally with-r'espect to the member-s5 and 6; Said screw also prevents accidental displacement of said pins 16 and 17,it beingunderstood however that byremoving the screw 18 the pins 16" v and 17 may be removed ed as to separatethe outwardly of the pins l6' and 17 through which the head 20 era bolt 21 is free to pass, said head being countersunlrin'theinner face of'thej aw member 6 and projeeting through the surface thereof and adaptedto be passed through an angular leg 22 on a handlemember 23 and clamped'to the jawmember 6by aj 'winged ni1t24j The aperture '19 in the memberf5 is not absolutely essential as ithe bolt 2limay be assembled beforeassembling the members 5 and 6 but by providing the aperturel9 the handle member may beat-7 jaw membersbandfii The member- 5 has a V i comparatlvely large aperture 19-arranged tached and detached without separating the jaw members 5 and 6.

Arranged in the handle member 23 is a key pin in the form of a bolt 25, the free end of which is adapted to enter an aperture 26 in the member 6 to prevent rotation of the handle member with respect to said member 6. At the same time, the bolt 25 serves to reinforce that part of the handle member through which it is passed, the head 25 of the bolt being preferably countersunk and a nut 27 is also countersunk in the inner face of the handle member as clearly seen in Fig. 8. The outer or free end of the handle member 23 has a hand grip 23 whereby the tool may be comfortably supported in the hand in such manner as to facilitate the movement of the tool over a surface to be scraped.

By providing a tool of the class described, it will be understood that scraper blades of any length up to the largest size may be arranged within and between the unobstructed surfaces of the jaw members Sand 6, the

screw 10 limiting the height of the blade, and it will be understood that the free cutting edge of the blade may project from the aws 5-6 to any desired extent depending upon the desires of the workman or the nature of the work being scraped. At the same time, the pins 16 and 17 may be adjusted to engage the side edges of blades of different widths so as'to prevent any possible shifting of the blade within and between the jaw members 5 and 6. V i

In Fig. 2 of the drawing, it will be understood that the tool is shown supporting a relatively narrow blade, the pins 16 and 17 being capable of wide extension with respect'to the members 5 and 6. It will also be understood that in clamping the blade 13 within and between the jaw members 5 and 6, said jaw members are capable of longitudinal movement with respect to each other in order to maintain the comparatively long bearing surfaces of the jaws 5"-6 in clamping engagement with the blade 13, and this operation is facilitated by virtue of the beveled face 9 on the block 7 It will be understood that while I have shown certain details of construction for carrying my invention into efiect, that I am not necessarily limited to these details and various changes therein and modifications thereof may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.
